论文部分内容阅读
1980年2月,美国矿冶石油工程师学会(AIME)于拉斯维加斯举行了第109届年会,在会上宣读了872篇文,其中有关铝合金压力加工方面的有72篇.AIME年会是一个世界性的学术年会,宣读论文的国家,除美国外,还有苏联、英国、日本、法国等几十个国家的科家和工程师.虽不能说由会上宣读的论文能看出工业先进国家在轻合金研究方面的进展全貌,但可部分地起“一斑见豹”的作用.在这72篇论文中,有关粉末冶金与复合材料的有22篇,几乎占28%;有关疲劳性能的有6篇;有关熔融铝安全方面的有7篇;有关含Li合金的有8篇.由此,我们不难探出国外在铝合金研究方面的“脉博”.特别对铝融体爆炸方面的研究,我国还是一个空白.此外,在这届年会上,还介绍了一些最新的工艺,例如分步熔化强化法、辊间淬火法,苏联成功地铸得了性能优良的直径800毫米的高强度铝合金(B95,?16)锭,等等.这些论文的一部分可在将来的有关书刊上看到,但不可能全部发表,为此,特编摘如下,供参考.
In February 1980, the American Society of Mining and Metallurgical Engineers (AIME) held its 109th Annual Meeting in Las Vegas, where 872 papers were read out, including 72 in the field of aluminum alloy pressure processing. The annual conference is a worldwide academic annual conference and country where papers are read out. Apart from the United States, there are also scientists and engineers from dozens of countries such as the Soviet Union, the United Kingdom, Japan, and France. Although it can not be said that papers We can see that the advanced countries in the industrialization of light alloys in the progress of the whole picture, but can be part of the The 72 papers, the powder metallurgy and composite materials, 22, accounting for almost 28 %; About fatigue performance of 6; about the safety of molten aluminum 7; about Li alloy has 8. Therefore, it is not difficult to explore abroad in the aluminum alloy research “Pulse Bo” In particular, China is still a blanket in its research on the explosion of aluminum melts, and at this annual meeting some of the latest techniques such as the step-by-step melt-hardening method and the inter-roll quenching method were introduced, and the Soviet Union succeeded in casting High performance aluminum alloy (B95,? 16) ingot with 800mm diameter, etc. These papers Part can be seen in the future about the books, but not all published, to this end, special ed pick below for reference.
