Dendritic coarsening model for rapid solidification of Ni-superalloy via electrospark deposition
(Elsevier, 2018-08-01)Control of splat thickness in an electrospark deposition (ESD) process can be used to improve the mechanical properties of deposited Inconel 718. The lower cooling rates of thicker deposition splats obtained through higher ... -
Effect of forging on the low cycle fatigue behavior of cast AZ31B Alloy
(Elsevier, 2017-08-26)The effect of forging on the low cycle fatigue (LCF) behavior of cast AZ31B was investigated. The forging process was conducted at a temperature of 450°C and speed of 390mm/min. Fully reversed (Rε=-1) strain controlled ... -
Effects of graphene nano-platelets (GNPs) on the microstructural characteristics and textural development of an Al-Mg alloy during friction-stir processing
(Elsevier, 2018-02-15)The aim of this research is to characterize the unique microstructural features of Al-matrix nanocomposites reinforced by graphene nano-platelets (GNPs), fabricated by multi-pass friction-stir processing (FSP). During this ... -
Effects of post-processing on the thermomechanical fatigue properties of laser modified NiTi
(Elsevier, 2019-01-01)The multifunctional capabilities needed for advanced shape memory alloys (SMA) actuators has been shown to be achievable by locally tuning the properties through laser processing. Before the wide-spread use of these SMAs ... -
Liquid metal embrittlement in laser lap joining of TWIP and medium-manganese TRIP steel: The role of stress and grain boundaries
(Elsevier, 2018-11-01)High-Manganese austenite-containing steels with superior combination of strength and ductility have shown potential for enhancement of passenger safety and body-in-white (BIW) weight reduction. Even though Zn-coated ... -
Pore network modeling of reaction-diffusion in hierarchical porous particles: the effects of microstructure
(Elsevier, 2017-07-24)A general framework based on pore network modeling is presented for simulation of reactive transport in a porous catalyst with a hierarchy of porosity. The proposed framework is demonstrated in the context of steady state ...
