Enhancing the mechanical properties and corrosion resistance of AISI 440C martensitic stainless steel via laser powder bed fusion and post-processing treatment
No full textAs the most typical high-strength stainless steel, the heat-treated AISI 440C steel has low machinability. It is also not weldable due to the high carbon content. Additive manufacturing, specifically laser powder bed fusion (LPBF), offers a promising solution for fabricating near-net shape components with this alloy. To address the limited research on the LPBF of AISI 440C steel, this work investigates the LPBF processability, microstructure and phase evolution of the AISI 440C steel, focussing on the role of post-processing treatments on improving mechanical properties, wear and corrosion resistance compared to its wrought counterpart. Our results indicate that highly dense AISI 440C components with > 99.98% relative density can be produced using optimised LPBF parameters. However, the low martensite start (Ms) temperature of the steel and the fast-cooling feature of the LPBF processing result in the formation of an austenite-dominant microstructure in the as-LPBF-fabricated parts with low strength and hardness. Post-processing treatment is required to enable the martensite transformation. Deep cryogenic treatment (DCT) at -196°C in liquid nitrogen had no effect, so conventional quenching and tempering were used. This facilitated M23C6 carbide precipitation, increased the Ms temperature and promoted martensitic transformation. After the heat treatment, the LPBF-fabricated AISI 440C steel exhibits significant improvements, including an ultimate tensile strength over 2.2 GPa compared with the as-LPBF-fabricated steel, enhanced toughness, doubled elongation (7.6%), and comparable hardness to the wrought counterpart. These improvements are attributed to the higher fraction of retained austenite with refined grains and precipitation of fine carbides. In addition, the heat-treated LPBF steel also exhibits the lowest specific wear rate, and superior corrosion resistance compared with the wrought 440C steel, due to improved passivation from the higher amount of retained austenite and finer carbides. The present results provide a foundation for broadening the practical applications of the AISI 440C steel via additive manufacturing
Research on Visualization of Surface Fire Spread Based on Triangle Mesh and Wang Zhengfei’s Improved Model
No full textWith the increasing frequency of global forest fires, research on the spread of forest fires has become one of the important directions in fire research. In order to improve the accuracy of surface fire spread simulation, based on relevant forest resources map preprocessing technologies, this paper takes the triangle mesh division idea of Tri-14 CA model for crowd evacuation and the Wang Zhengfei’s improved forest surface fire spread speed model as the basis, obtains the basic equation set of forest fire spread speed in 14 directions, and establishes the spatio-temporal spread mathematical model of forest surface fire. Based on the above, a software platform is established by applying computer technology to realize the calculation and visualization simulation of forest fire spread. Combined with examples, the correctness and practicability of the model software are illustrated, aiming to provide information support for forest disaster emergency departments
Comment on “An equable subtropical climate throughout China in the Miocene based on palaeofloral evidence” by Qing Wang, Yan Li David K. Ferguson, Wen-Bo Mo, and Nan Yang, Earth-Science Reviews, [Earth-Science Reviews 218 (2021) 103649]
No full textIn their thoughtful paper entitled “An equable subtropical climate throughout China in the Miocene based on palaeofloral evidence”, Qing Wang, Yan Li, David K. Ferguson, Wen-Bo Mo, and Nan Yang (2021) imply that China exhibited negligible latitudinal mean annual precipitation (MAP) gradients and lacked arid regions during the Miocene. They also speculate that there was no abrupt change in elevation of the Tibetan Plateau, nor that the plateau attained its present altitude or orography during that period. These conclusions were derived mainly by using a co-existence approach (CA) and ‘incomplete data’. Here, we use CA with training data and also integrate a coexistence likelihood estimation, a pollen-MAP boundary, a desert-MAP boundary, and other newly published MAP data to show that Northwest China consistently exhibited drier conditions than South China and East China during the entire Miocene, with our new values being 300–500 mm lower than those of Wang et al. (2021). This implies that there were large spatial gradients of MAP in China during the Miocene, which may be directly linked with the growth of the Tibetan Plateau, the global cooling, as well as other factors. We recommend the comprehensive consideration of multiple methods and proxies for reconstructing past climate conditions as opposed to a single proxy

Detection of Novel Variations Related to Litter Size in BMP15 Gene of Luzhong Mutton Sheep ( Ovis aries)
No full textLitter size is an important economic trait in the mutton sheep industry. BMP15 is one of the key candidate genes for litter size in sheep. In this study, the entire ORF region of BMP15 was sequenced in 154 Luzhong mutton ewes, and the novel variations were determined. The association between polymorphism in BMP15 and litter size was analyzed using a general linear model. Six out of a total of thirteen variations were identified to be novel. Association analysis indicated that four (SNPs ENSOART00000010201.1:c.352+342C>A, c.352+1232T>C, c.352+1165A>G and c.353-2036T>A) were significantly associated with litter size. The joint analysis among three major genes (BMP15, BMPR1B and GDF9) exhibited significant interaction effects in three combinations (FecB and c.352+1232T>C of BMP15; FecB and c.352+1165A>G of BMP15; c.352+342C>A of BMP15 and ENSOART00000014382.1:c.994G>A of GDF9). For the SNPs c.352+1232T>C and c.352+342C>A, the global distribution of allele frequencies showed that the highest variation frequency occurs in Western Europe. In conclusion, the results demonstrated that BMP15 is a major gene for litter size in Luzhong mutton sheep and candidate SNPs associated with litter size were identified
