in order to improve the liquation of mc5 cold roll blank and the strip quality, the high temperature diffusion annealing of the ingot.
为改善mc5冷轧辊辊坯的液析、带状质量,钢锭要进行高温扩散退火。
squeeze casting of an ly12 (2024) alloy was carried out to investigate the effect of applied pressure and followed diffusion annealing on microsegregation in the alloy.
研究了ly12合金在挤压铸造中不同压力以及后续扩散退火制度对铸锭微观偏析的影响。
the result of the investigation shows that za27 alloy by diffusion annealing is suited for cold extrusion processing method, the proportion of finished product of the element was 100%.
结果表明,经扩散退火处理的za-27铸造合金适用于冷挤压成型方法,制件的成品率为100%。
the microstructures, inclusions and of steels before and after diffusion annealing was compared by means of microscope and electron probe micro-analyzer (epma).
利用金相显微镜和电子探针分析了扩散退火前后碳钢的金相组织、夹杂物和磷偏析的变化情况。
it is found that shock toughness of powder forging part can be increased obviously by diffusion annealing for long time.
发现长时间扩散退火可显着提高粉末锻件的沖击韧性。
the preparing method comprises brushing material, solid-phase composition, diffusion annealing and cold rolling.
其制造方法包括刷料、固相复合、扩散退火、和冷轧工艺步 骤。
