Abstract:
PART I - Creep Tests of 150 hours Duration at 100 deg., 150 deg. and 200 deg. C. on some Cast Magnesium Alloys. PART II - Comparison of the Creep Properties of Three Cast Magnesium Alloys Based on Tests of 1,000 hours Duration. PART III - Effect of Various Heat Treatments on the Short-time Creep Behaviour at 3 ton/sq.in., 150 deg. C., of Four Cast Magnesium Alloys. The National Physical Laboratory was represented at a meeting held at the Ministry of Aircraft Produ.ction on 21st July, 1943, when certain proposals for research into the properties of magnesium alloys at temperatures up to 200 deg. C. were discussed. It was decided that the N.P.L. should be asked to undertake some short-time creep tests on a number of magnesium alloys with a view to selecting suitable alloys for fuller investigations. It was agreed that creep tests of short duration at 100, 150 and 200 deg. C., and at one stress to be selected for each temperature, should first be undertaken, and that subsequent tests should be made on those alloys which appeared to warrant more prolonged creep testing.
