The tensile properties of plutonium gallium alloys in the temperature range 20–100° C

Mechanical behavior of δ-phase Pu–Ga alloys. Part II: Model verification and application

“…Hecker's data for a Pu-1.75at.%Ga alloy [6] fall well within 1 standard deviation, indicating that the material's work hardening is, in fact, insensitive to Ga content. The data of Miller and White [4], however, contradict this observation. These data exhibit a clear trend of decreasing ultimate tensile strength with decreasing Ga content.…”

“…These data along with the torsion data of Wheeler and Robbins [2] were used to determine the MTSmodel parameters for Pu-Ga alloys. To validate the model, we compare predictions of the model to uniaxial yield and ultimate strengths as Hecker and Morgan [3], Miller and White [4], Beitscher [5], and Hecker [6] report.…”

Mechanical properties of delta-stabilized Pu–1.0 wt% Ga alloys

“…Data from Beitscher [28] between strain rates of 2 · 10 1 and 2 · 10 3 /s are consistent for cast, homogenized, rolled and recrystallized delta properties. Flow stress data from Miller et al [29] for chill cast and homogenized delta is in line with the lower strain rate curves in Fig. 8.…”

“…Consequently, most of the mechanical property information that has been published is for Pu-Ga binary alloys with emphasis on the 1.0 wt% (3.34 at.%) alloy. The largest body of data on this alloy was published in the decade between 1965 and 1975 [5][6][7][8][9]11,12,14,[16][17][18][21][22][23][25][26][27][28][29][30][31][32][33][34][37][38][39][40][41][42][43][44][45][46], with limited studies since that time [10,13,24,35]. Fig.…”

Study of homogenization rates in plutonium--1 weight percent gallium alloy as a function of percent reduction by cold rolling

“…The effect of a change of concentration gradient on the homogenization time may be expressed by the equation gallium is shown in Figure 29. 15 In addition, the mechanical properties of Pu-1 wt % Ga (as-rolled),16 Pu-0.9 wt % 'oa? and unalloyed plutonium" are compared in Table 4.…”
