Published dath on the BETA solid solution decomposition mechanism of Ti with 11 wt.% Mo showed that at 200 to 400 C the BETA solid solution decomposed through an intermediate phase ( BETA sintered BeO BETA + sintered BeO alpha + BETA ). After long periods of treatment at increased temperature, transformation to the alpha phase occurs at 500 C the BETA solid solution transformed directly into alpha phase. Tests carried out with position mechanisms. Beta solid solutions with 11, 15, 20, and 93 wt.% Mo are stable at 100 to 2450 hours, respectively, at negative and room temperature; at 100 it is stable for 100 hours and at 200 C it is stable for 4 and 81 hours. The 20 and 93 wt.% Mo BETA solid solutions remain stable for some time at 300,400, and 500 , while solutions with 11 and 15 wt.% Mo disintegrate. The high Mo content solutions remain stable for 1 hour at 300 and 500 C and for 45 min at 400 C. Maximum hardness was found in the BETA + phase. At 400 C it is harder than at 200 to 300 C. (R.V.J.)
