Abstract
The reverse bend crack test-in some cases, slit type specimen crack test-was applied to several casting aluminum alloys of Japanese specifications which were the objects of fish-bone type crack test in the previous paper. The results are shown in Fig. 3 and Fig. 5-8 as the function of the chemical compositions of alloys, and are compared with similar results obtained by other authors. Some notes on the crystal behaviours of weld metals are given.
