Compatibility between Be12Ti and SS316LN

General properties on compatibility between Be–Ti alloy and SS 316LN

“…In this figure, the growth rate of Be in Ref. [6] is in accordance with the experimental equation obtained by Hofmann et al [9]. The growth rate of Be-Ti alloys in the present study was smaller than that of Be, and it decreased with an increase in Ti content in the Be-Ti alloy.…”

“…6 shows the relationship between the content of titanium and the thickness of the reaction layer using the results of the present study and Ref. [6]. This figure also shows the component of Be-Ti [8].…”

“…Compatibility tests were carried out at 600, 700 and 800 • C by annealing the diffusion couples in an electric furnace under vacuum conditions. Annealing times were 100, 300 and 1000 h. In the previous paper [6], similar compatibility tests were carried out for Be and Be-8.5at%Ti with SS 316LN. After annealing, the interaction in the diffusion couple was analyzed as follows:…”

“…1 shows the microstructures of Be-5at%Ti and Be-7at%Ti. This figure also shows microstructures of hot pressed high purity beryllium (S65C) and Be-8.5at%Ti (Be 12 Ti fabricated by a hot isostatic pressing (HIP) method) before compatibility tests [6] for comparison. The Be-phase in the specimens decreases with increasing Ti content.…”

“…In previous papers, compatibility of Be and Be 12 Ti with SS 316LN was evaluated [5,6]. In the results, the thickness of the reaction layer between Be 12 Ti and SS 316LN was smaller than that between Be and SS 316, and the thickness for Be 12 Ti was one tenth of that for Be at 800 • C. However, Be 12 Ti is brittle, and it is difficult to fabricate pebbles from it.…”
