利用万能力学试验机测量了经电渣净化后的ZL205A的抗拉强度和伸长率。结果发现,经电渣净化后的ZL205A的抗拉强度和伸长率大幅下降。利用直读光谱仪分析净化后试样的成分,发现净化后的ZL205A中Ti含量减少近48%。通过在净化后的铝熔体中补加Al-Ti中间合金,测量试样的力学性能,发现其抗拉强度为486.29MPa,和净化前的相当,但伸长率为11%,比净化前提高了100%。 Tensile strength and elongation of ZL205A after electroslag purification were measured by universal mechanical testing machine. The results showed that the tensile strength and elongation of the ZL205A after the electroslag purification greatly decreased. Analysis of the purified sample using a direct-reading spectrometer revealed a nearly 48% reduction of Ti content in the purified ZL205A. Through the addition of Al-Ti master alloy to the purified aluminum melt, the mechanical properties of the sample were measured and found to be 486.29MPa, equivalent to that before purification but with an elongation of 11% Increased by 100%.
