Book Description
Appreciable strength levels were retained to 650 C in a Ti-10Al-1Si alloy aged in the (alpha alpha sub 2) phase field to yield optimum room temperature strength and ductility. The aging treatment precipitated a uniform distribution of alpha sub 2-particles such that, at room temperature, dislocations bypassed instead of shearing the particles at low strains. Specimens fractured at room temperature exhibited fine uniform dimples even for those aging conditions that imparted no macroscopic ductility. The main crack appeared to propagate through the planar slip bands that had cut through the alpha sub 2-particles. A two-step aging process produced a higher volume fraction of bimodally distributed alpha sub 2-particles that led to higher strength levels at elevated temperatures. Both for the single size and the bimodal alpha sub 2-particle distributions, elevated-temperature deformation structures consisted mainly of planar slip bands that sheared through the alpha sub 2-particles.

Dynamic Strain Aging During the Creep and Tensile Testing of a Molybdenum-titanium-carbon Alloy

Dynamic Strain Aging During the Creep and Tensile Testing of a Molybdenum-titanium-carbon Alloy PDF Author: Peter L. Raffo

ISBN:
Category : Deformations (Mechanics)
Languages : en
Pages : 36

Book Description
A study was made of the influence of dynamic strain aging on the creep and short time tensile properties of a Mo-0.82 Ti-0.20 C (at. %) alloy. The strengthening effects are directly related to carbide precipitation during deformation. The precipitation lowers the density of mobile dislocations and slows down Ihe rate of recovery.
