Title: Strain partition and rupture analysis of notched tensile multilayered steel specimens

Abstract

Multilayered steel composites consisting of alternating martensitic and austenite layers were successfully fabricated with a combination of high strength and ductility. In situ SEM tensile experiments were performed to investigate the fracture processes. Results indicated that the martensitic layer distributed between two ductile austenite layers has better deformation ability, and the dimple fracture mode dominated the fracture of the whole specimen. In situ synchrotron microbeam X-ray diffraction experiments were carried out to study the microscopic deformation in austenitic layer and martensitic layer ahead of notch root under incremental tensile loading. Results indicated that for austenite layer, the maximum strain is located in the middle of the layer at the lower applied load. When at the higher applied load, larger strain is concentrated on the notch root. For martensitic layer, uniform strain is distributed at the region at the lower applied load, with increasing the applied load, small strain appears in the middle of martensitic layer. However, the variation in the strain in the martensitic layer is relatively smaller, which is actually affected by both the notch and the ferrite content in the martensitic layer. Furthermore, the changing trends of the strain in the austenite layer and martensitic layer can stillmore »« less

In-situ SEM observations of crack nucleation and propagation in a notched tensile specimen of Ni{sub 3}Al with boron

Journal Article Xu, Y ; Schulson, E M ; Domaine Univ., Saint Martin d`Heres - Scripta Materialia

Recently, the notch sensitivity of the ductile intermetallic alloy, Ni{sub 3}Al with boron, was studied by Xu and Schulson. It was found that when a thick specimen (thickness {ge} 1.4 mm) containing a sharp notch (Notch root radius {le} 0.04 mm) was strained, the material suffered from a loss of ductility: the reduction in area was reduced from about 33% to about 15% and the fracture mode changed from ductile transgranular to a 50/50 mixture of transgranular and intergranular. Experimental results and numerical simulation both suggested that cracks initiated around the notch tip where both the tensile stress and themore »« less

Load partitioning and strain-induced martensite formation during tensile loading of a metastable austenitic stainless steel.

Journal Article Hedstrom, P ; Lindgren, L E ; Almer, J D ; ... - Metall. Mater. Trans. A or B

In-situ high-energy X-ray diffraction and material modeling are used to investigate the strain-rate dependence of the strain-induced martensitic transformation and the stress partitioning between austenite and {alpha}{prime} martensite in a metastable austenitic stainless steel during tensile loading. Moderate changes of the strain rate alter the strain-induced martensitic transformation, with a significantly lower {alpha}{prime} martensite fraction observed at fracture for a strain rate of 10{sup -2} s{sup -1}, as compared to 10{sup -3} s{sup -1}. This strain-rate sensitivity is attributed to the adiabatic heating of the samples and is found to be well predicted by the combination of an extended Olson-Cohenmore »« less

In-situ EBSD study of deformation behavior of retained austenite in a low-carbon quenching and partitioning steel via uniaxial tensile tests

Journal Article Li, Wan-song ; Gao, Hong-ye ; Nakashima, Hideharu ; ... - Materials Characterization

Through using in-situ electron back-scattered diffraction and uniaxial tensile tests, this work mainly focuses on the deformation behavior of retained austenite (RA) in a low-carbon quenching and partitioning (Q&P) steel. In this paper, three different types of RA can be distinguished from different locations, respectively, RA grains at the triple edges, twinned austenite and RA grains positioned between martensite. The results have shown that grains at the triple edges and twinned austenite could transform easily with increasing strain, i.e. are less stable when compared with RA grains distributed between martensite that could resist a larger plastic deformation. Meanwhile, the strainmore »« less

Notch Tensile Behavior of the Mg-Zn-Gd-Zr Alloy

Journal Article Chiranth, B. P., E-mail: chiranthbp.bellur@gmail.com ; Siddaraju, C. ; Ram Prabhu, T. - Journal of Materials Engineering and Performance

The Mg-Zn-Gd-Zr alloy is one of the important aerospace alloys in the aircraft gearbox applications. The complex geometry of the gearbox introduces several stress concentration points with various intensities. These regions are susceptible to catastrophic failure under mixed loading condition. Therefore, it is important to understand the deformation and failure mode of this alloy for various plastic constraint conditions. In the present work, Mg-4%Zn-1.5%Gd-0.5%Zr alloys were prepared with four different increasing notch root radii (1, 2, 4 and 8 mm). These samples were tested for tensile properties and compared with the smooth condition. In addition, notch sensitivity was determined analytically. Themore »« less
