LY12铝合金超塑性挤压工艺的试验研究

Experimental study on superplastic extrusion technology of aluminium alloy LY12

通过试验制定了铝合金ＬＹ１２的超塑性挤压工艺。用此工艺可成形较复杂的、高精度的ＬＹ１２合金制件，并且生产率高，可达批量生产的能力。

in this paper, superplastic extrusion technology of aluminium alloy LY12 is laid down by experiment. Using this techology, more complicated and accurate products of alununium alloy LY12 can be formed and higher productivity and lot production can be reached.
