between surface quality and mechanical properties of the part. A direct application is the evaluation of surface quality of thixoforged thin wall parts made of 7075 aluminium alloy. Key words... wrought alloy chosen for experiments is the 7075 aluminium alloy composed by Al-5.88Zn-2.45Mg-1.54Cu-0.2Cr-0.18Fe- 0.1Si-0.06Mn-0.025Ti-0.025Zr (mass fraction, %). Its solid fraction fits to high......
Gas Quenching during Age Hardening of the Aluminium Casting Alloy AI-7Si-0.3Mg A.Rose1,H.W.Zoch1,F.Hoffmann1,O.Kessler1 (1.Stiftung Institut fur Werkstofftechnik, Bremen, Germany) 摘要:For quenching of age hardenable aluminium alloys today predominantly aqueous quenching media are used.which can lead due to the Leidenfrost phenomenon to a non-uniform cooling of the parts and thus to thermal......
