Abstract

1,254,884. Making pistons; extruding; working at specified temperatures. ASSOCIATED ENG. Ltd. 26 March, 1970 [30 Dec., 1968], No. 61776/68. Headings B3A, B3P and B3V. [Also in Division F2] A piston is made by backward extruding an alloy slug 20 which has been heated to a temperature range in which it is superplastic. The alloy may be aluminium-silicon with small amounts of alloying substances such as copper and magnesium. The temperature range for this alloy to render it superplastic is 200-300‹ C. and the slug may be heated before insertion into the die 21 or the die may be heated. The slug is cut from a length of continuous casting. After shaping the piston is machined to form gudgeon pin bores and ring seats.
