IntroductionTungsten possesses a high melting point, high hardness, and excellent corrosion and radiation resistance, offering broad application prospects in the field of thermonuclear fusion. Particularly within the International Thermonuclear Experimental Reactor (ITER) project, tungsten is regarded as an ideal material for plasma-facing components [1-2]. However, its brittleness at room tempera
Read MoreHigh-entropy alloys (HEAs) typically contain five or more major elements, with each constituent present in equimolar or near-equimolar ratios. This alloy design concept was first proposed in 2004 by Professor Yue Junwei and his research team at National Tsing Hua University, Taiwan [1]. Unlike traditional alloys, HEAs exhibit high-entropy effects, hysteretic diffusion effects, lattice distortion e

However, early hip resurfacing procedures demonstrated shorter prosthesis longevity compared to total hip arthroplasty. In the early 1990s, McMinn et al. [2] in the UK and Wagner et
Read MoreHot isostatic pressing (HIP) is a technology that applies isostatic pressure to powder metallurgy products or compacts using high-pressure gas at elevated temperatures. This process eliminates internal defects and voids within the product while simultaneously inducing grain boundary diffusion bonding at high temperatures. This improves the mechanical properties of the product and achieves complete
