 note = {The author has studied mechanical properties of aluminum coated steel and carried out an experiment, expecting that the aluminum coating on steel might prevent various kinds of alloy from stress corrosion cracking. The author first has studied the effects of aluminum coating and of heat-treatments on stress corrosion cracking of 18-8 austenitic stainless steel using a pure tension specimen in 42% boiling MgCl₂ solution (b. P143℃) and boiling 20% NaCl solution (b. P102℃) The results obtained were as follows (1) As the results of rupture test of the specimens, it was proved that there was no effect of heat treatments on stress corrosion cracking of 18-8 austenitic steel in boiling 42% MgCl₂ solution and its apparent threshold stress was about 10kg/mm². On the contrary, the effects of heat treatment were remarkable in boiling 20% NaCl solution, (2) All the paths of crack of specimens were trans-crystalline in Mgcl2 solution and inter-granular in NaCI solution. (3) In aluminum coated 18-8 austenitic stainless steel, no rupture or etch pit was found after 200h. test in MgCl₂ solution and 500h. test in NaCl solution. (4) Weight loss per unit area in coated aluminum increased both with the increase of applied stress and with the decrease of coated area of aluminum. (5) Current dencity between 18-8 austnitic stainless steel and coated aluminum in MgCl₂ or NaCl solution was higher than that which was required to prevent the steel from creating and propagating Craks., Article, 信州大学工学部紀要 24: 63-72 (1968)},
