冶金学

Coming to the fifties of the 20th century, metallography developed successively into physical metallurgy and materials science

到了二十世纪中叶，金相学已逐步发展成金属学、物理冶金和材料科学。

During the production scheduling, the metallurgist would fully utilize metallurgical transaction controlled rolling, precipitation, etc.

在制定生产规程时冶金师将充分利用金属学转变，以产生首选的组织结构和尽可能好的成品性能。

Besides , some unfathomed problems about application of stereology and image measurement in industry have been raised .

体视学，图象检测技术在冶金工业中的应用及进展

Tight alloying layer with undulation and without visual pocket and inclusion has been obtained by experiment.The alloying layer is metallurgically combined with the matrix.

试验结果获得了致密、无肉眼可见气孔、夹杂、熔覆表面有一定起伏的合金层，合金层与基体间完全冶金结合；熔覆合金层由单相Fe3 Al构成，覆层组织为粗大的柱状晶团，柱状晶团内包含大量极细小的板条状Fe3 Al晶粒，一些相邻的板条晶之间具有基本相同的晶体学取向。

Dense alloy coating without pore and inclusion is obtained which metallurgically bonded with steel but existing a few cracks. The results show that the cladding alloy coating is mainly composed of single-phase Fe3Al, and the microstructure is coarse equiaxed grain-groups that consist of large amount of fined slug like Fe3Al grains, between which some adjacent grains have the similar orientation.

试验获得了致密、无肉眼可见气孔、夹杂的合金层，合金层与基体间完全冶金结合，但存在裂纹现象；熔覆合金层主要由单相Fe3Al构成，覆层组织为粗大等轴状晶团，等轴状晶团由大量极细小的条状Fe3Al晶粒构成，一些相邻的条状晶粒之间具有基本一致的晶体学取向。

Recently, the advocates of "breaking in" harmonicas have claimed that the procedure is akin to a metallurgical process called "coaxing".

最近，有&开琴&的鼓吹者声称此过程类似于冶金学的的&coaxing&处理，但是权威资料显示并非如此

The effect of austempering on the wear resistance of austempered ductile iron was studied.

等温淬火球墨铸铁(Austempered Ductile Iron，简称ADI)是近30年来铸铁冶金学方面的重大成就之一[1]。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

到它被攻陷的时候，里面多数的犯人是写了反对政府贪污文章的作家。

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
