Investigation of metastable γ′ precipitate using HRTEM in aged Cu–Be alloy

The precipitation behavior and strengthening of a Cu–2.0wt% Be alloy

“…3(a). An approximate orientation relationship [13] for g 0 is found to be (1-13) a 99(130) g 0 , [110] a 99//[001] g 0 , which can be seen in Fig. 3(c) and (d).…”

Stress-assisted nucleation and growth of γ″ and γ′ precipitates in a Cu–1.2 wt%Be–0.1 wt%Co alloy aged at 320°C

“…The γ' precipitates had a plate-like shape parallel to {113} α or {112} α ( Figure 9) [12,18]. Each orientation relationship has six variants and thus there are twelve variants in Table 2.…”

An Investigation of the Effects of Ageing Parameters on Wear Behaviours and Electrical Conductivity of Cu-Co-Be Alloys

“…It is understood from the EDS analysis results given in Table I that these precipitates are Co-and Be-rich. According to Yağmur et al [5], metastable γ precipitates grow and transform to stable γ precipitates as the duration of the ageing treatment increases. It is also observed that second phase precipitates are distributed homogeneously in the structure of alloy.…”

“…Dimensions and distribution of the second phase precipitates formed in the structure with ageing are important factors in increasing the strength and hardness. The Guinier-Preston (GP) zones formed in the structure at the first stage of ageing transformed to γ metastable phase and γ stable phase with the increasing ageing time [3][4][5]. Previous studies report that the wear behaviour of the alloy can be improved depending on the ageing conditions [6,7].…”
