日本一所大学的研究人员研究出一种提高不锈钢强度的新技术。该项技术是首先利用一种强力粉碎机对市售的不锈钢粉末进行再粉碎 ,并施加强力进行揉合。然后 ,将不锈钢粉末装入模具中 ,在 80 0℃的高温下烧结。这种技术实际上就是制造精密材料使用的非平衡粉末冶金法。采用这种方
Researchers at a Japanese university have developed a new technique to increase the strength of stainless steel. The technique is to first re-pulverize commercially available stainless steel powder with a powerful grinder and apply strong kneading. Then, the stainless steel powder was charged into a mold and sintered at a high temperature of 80 ° C. This technique is in fact the non-equilibrium powder metallurgy method used to make precision materials. Use this side
