This paper presents a probabilistic framework for the modeling of fatigue damage in three gamma-based titanium aluminides: Ti-45Al-2Mn-2Nb+0.8 vol% TiB 2 , Ti-47Al-2Mn-2Nb+0.8 vol% TiB 2 and Ti-48Al-2Cr-2Nb (all compositions quoted in atomic percent unless stated otherwise). This includes: empirical stress life and fracture mechanics approaches to the estimation of material reliability...
This paper presents measurements of the plasticity length scale for polycrystalline LIGA nickel foils produced by electroplating in a sulfamate bath. The micro-bend test method developed by Stolken and Evans [Acta Mater. 46 (1998) 5109] is used to obtain a composite length scale parameter, l c that is primarily associated with rotational gradients. The micro-bend test utilizes the measurement...
