上海铝材一厂职工,试验成功在纯铝材料中增加微量的钛,能显著地提高和改善材料的机械性能,延长铝制品的使用寿命,并能有效地降低铝材中的“起皮气泡”废品率。在纯铝材料中增加微量的钛后,其主要作用在于细化铝的晶粒度,从而使材料的强度,延伸、深冲性能等得到不同程度的提高。同时,由于晶粒度的细化,可有效地减少铝材中的“起皮气泡”缺陷,提高产品质量和降低成本。据生产实践表明,过去不加钛的铝板加工
Shanghai Aluminum Plant workers, the successful trial in the pure aluminum material to increase trace titanium can significantly improve and improve the mechanical properties of the material to extend the life of aluminum products, and can effectively reduce the aluminum in the “skinning bubble ”Rejection rate. In the pure aluminum material to increase trace titanium, its main role is to refine the grain size of aluminum, so that the material strength, elongation, deep drawing properties have been improved to varying degrees. At the same time, due to grain refinement, can effectively reduce the aluminum “blister” defects, improve product quality and reduce costs. According to production practice shows that in the past without titanium processing of aluminum
