First crystallization, graphitizing annealing technology and cutability are developed in this article.
本文则进一步研究耐热球墨可锻铸铁的一次结晶过程和石墨化退火工艺以及它的硬度指标和切削加工性之间的关系。
s excellent cutability is that lead particle has not intension and has the role of lubricating at the same time. Our experiment is based on realizing the mechanism of leaded brass?
含铅黄铜之所以具有优良的切削性能，是由于铅质点能起到断屑作用，且具有润滑效果。
