Abstract

Using electron backscatter diffraction, the microstructural features of tension–compression–tension (T–C–T) tertiary twins are studied in coarse-grained pure polycrystalline magnesium subjected to monotonic compression along the extrusion direction in ambient air. T–C–T tertiary twins are developed due to the formation of a compression–tension double twin inside a primary tension twin. All the observed T–C–T twin variants are of T_iC_jT_j type. T_iC_i+1T_i+1 (or T_iC_i–1T_i–1) variants are observed more frequently than T_iC_i+2T_i+2 (or T_iC_i–2T_i–2) variants. Moreover, the number of tertiary twin lamellae increases with the applied compressive strain.

Pre-compression effect on microstructure evolution of extruded pure polycrystalline magnesium during reversed tension load

Journal Article Culbertson, Duke ; Yu, Qin ; Wang, Jian ; ... - Materials Characterization

Highlights: • Number of twin variants under compression along ED is dependent on grain orientation. • Tension after pre-compression results in low-SF twinning and secondary twinning. • Secondary twinning is facilitated by increasing pre-compression. • Sub-grains due to twinning enhance material strength. - Abstract: The microstructure evolution of extruded pure polycrystalline magnesium under compression followed by subsequent tension in ambient air was investigated. Solid round dog-bone shaped specimens were compressed along the extrusion direction (ED) to − 7.3% and − 12.8% true strains, respectively, and then tensioned along the ED to failure. Electron backscatter diffraction (EBSD) was used to examinemore »« less

In Situ Characterization of the Effect of Twin-Microstructure Interactions on {$$1 0 \bar{1} 2$$} Tension and {$$1 0\bar {1} 1$$} Contraction Twin Nucleation, Growth and Damage in Magnesium

Journal Article Russell, William D. ; Bratton, Nicholas R. ; Paudel, YubRaj ; ... - Metals

Through in situ electron backscatter diffraction (EBSD) experiments, this paper uncovers dominant damage mechanisms in traditional magnesium alloys exhibiting deformation twinning. The findings emphasize the level of deleterious strain incompatibility induced by twin interaction with other deformation modes and microstructural defects. A double fiber obtained by plane-strain extrusion as a starting texture of AM30 magnesium alloy offered the opportunity to track deformation by EBSD in neighboring grains where some undergo profuse {more »« less

Tension–Compression Asymmetry Improved by Cold Extrusion in Pure Magnesium

Journal Article Li, Cheng-jie ; Cheng, Shuang ; Sun, Hong-fei ; ... - Journal of Materials Engineering and Performance

In this paper, cold extrusion was successfully used to fabricate the fine-grained pure Mg bar with average grain size of 2.5 μm. The microstructure, texture and mechanical properties were evaluated by electron backscattering diffraction and mechanical test. The results showed that the corresponding yield strengths for as-extruded fine-grained pure Mg were 130.8 MPa in tension and 125.6 MPa in compression, leading to a greatly improved yield asymmetry ratio. The improvement in tension–compression asymmetry is mainly due to grain refinement which favors the suppression of deformation twinning in compression and promotion of multi-deformation modes both in tension and compression at small strains.

Twinning-detwinning behavior during cyclic deformation of magnesium alloy

Journal Article Lee, Soo Yeol ; Wang, Huamiao ; Gharghouri, Michael A. - Metals

In situ neutron diffraction has been used to examine the deformation mechanisms of a precipitation-hardened and extruded Mg-8.5wt.%Al alloy subjected to (i) compression followed by reverse tension (texture T1) and (ii) tension followed by reverse compression (texture T2). Two starting textures are used: (1) as-extruded texture, T1, in which the basal pole of most grains is normal to the extrusion axis and a small portion of grains are oriented with the basal pole parallel to the extrusion axis; (2) a reoriented texture, T2, in which the basal pole of most grains is parallel to the extrusion axis. For texture T1,more »« less

Study of growth twins produced through heat treatment of fine-grained magnesium

Journal Article Li, Qizhen - Materials Science and Engineering. A, Structural Materials: Properties, Microstructure and Processing

This study investigated the microstructural features of magnesium after the fine-grained magnesium sample was heat treated at 400 °C for 2 h. Both fine-grained and heat-treated magnesium samples were observed using the electron backscatter diffraction technique in scanning electron microscopy. The results show that the grains were substantially coarsened, the local strain and the local misorientation was significantly reduced, and a large number of twins were observed in the heat-treated magnesium sample. The misorientation angle analysis determined that the twins were oriented about 86.3° away from the orientation of their corresponding matrices, and the twins were the variants ofmore »« less
