Determination of elastic constants of additive

May 01, 2020 · Recent advances in ultrasonic-based equipment enable the use of laser ultrasonic and pulsed ultrasonic polar scan (P-UPS) methods to measure elastic constants of materials [26,27,28]. Zhan et al. [ 26 ] utilized a laser ultrasonic method to determine the elastic constants of fiber-reinforced composites when a transversely isotropic assumption Estimation of SingleCrystal Elastic Constants from Apr 13, 2004 · In this paper we explore a method for deducing the singlecrystal elastic constants of a metal using the combined ultrasonic and metallographic data for a polycrystalline specimen. We specifically consider the case seen in the jetengine alloys:polycrystalline cubic microstructures having equiaxed, randomly oriented grains.

Non-contact measurement of elastic modulus by using laser

May 15, 2015 · Non-contact measurement of elastic modulus is necessary for the in-line assessment of material in harsh environments such as high temperature. In this paper, a fully non-contact method to measure elastic modulus is proposed based on the laser ultrasonic technique (LUT) that uses a short-pulsed laser to generate ultrasound and the other laser coupled to an interferometer using a Stacking fault energy in concentrated alloys Nature Jun 11, 2021 · The elastic constants used here are C11 =249.4GPa, C12 =159.0GPa, and C44 =.4GPa from Laplanche et al. 29.

The Elastic Constants of the Single Crystal of the Mg-Zn

Elastic constants are determined of appropriate experiments on single crystals. Growing the artificial single crystals of the desired size is associated with technical difficulties. Using the elastic constants of a single crystal of pure metal for calculating properties of alloys in polycrystalline state can lead to significant errors.The Elastic Constants Measurement of Metal Alloy by Using The Elastic Constants Measurement of Metal Alloy by Using Ultrasonic Nondestructive Method at Different Temperature Figure 7 The elastic modulus of 3J53 alloy corresponding to different temperature.
