Research Status and Prospects of Corrosion Resistance of High Entropy Alloys by SHENG Yinghang, WANG Kai, GAO Peng, CUI Tong, LI Fuli, WANG Zhiquan, SUN Bugong, LI Bo, GUO Hongjian

“…High Entropy Alloys (HEA) are a new type of metal material with broad application prospects in the high-end equipment manufacturing industry.Due to the unique phase structure and “four major effects” of high entropy alloys， which endow them with excellent mechanical properties such as strength，hardness，toughness and wear resistance，high entropy alloys have become a research hotspot in the field of materials.Corrosion is a common and unavoidable form of failure in metallic materials，and high entropy alloys are widely used in industrial fields due to their excellent corrosion resistance.Thus， it is necessary to focus on studying the corrosion resistance performance， corrosion resistance mechanism and laws of high entropy alloys for better developing high-performance high entropy alloys.This article firstly briefly described the definition and classification of high entropy alloys， then summarized the preparation methods of high entropy alloys， and provided a detailed overview of the research status of high entropy alloy corrosion resistance.Different preparation processes and process parameters had a direct impact on the microstructure of high entropy alloys， and high entropy alloy components had broad design space.Therefore， by adjusting the preparation process parameters and component composition， the corrosion resistance of high entropy alloys could be further optimized.At last，the research topics and ideas for future high entropy alloys were discussed.…”

ANALYSIS OF THE PRESSURE DISTRIBUTION ON RAIL SEAT OF CONCRETE SLEEPERS UNDER 40- TONNE AXLE LOAD by AN BoYang, YANG JiZhong, LIU Chao, ZHAO Xin, WEN ZeFeng, JIN XueSong

“…More results have shown that（ 1） the typical heavy haul track structure in China can meet the requirements of 40- tonne axle load,but the stress on the top of subgrade exceeds the bearing capacity considered in normal design;（ 2） with the increase of the lateral wheel-rail contact force,the width（ along the lateral） of the contact patch between the railpad and the sleeper decreases and the length keeps almost unchanged,thereby the maximum pressure increases and its location moves towards the field side in the lateral;（ 3） Under the typical wheel-rail contact forces,the pressure distribution on the rail seat changes significantly when the stiffness of the railpad increases from 80 MN / m to 200 MN / m,while un-affected as the stiffness further increases to 1300 MN / m;（ 4） Assuming a constant dynamic amplification factor,the pressure on the rail seat decreases as the rail fastening system fails,and correspondingly,the shape of contact patch between the rail pad and the sleeper becomes more irregular due to less constraints.…”
