The effect of martensite ordering on shape memory effect in a Copper-Zinc-Aluminium alloy
TL;DR: In this article, the shape memory effect (SME) and the degree of ordering in martensite formed through various heat-treatment processes, e.g. ice water quenching, step-quenching and aging etc., has been studied in a Cu-25.83wt. %Zn-3.96wt.
Journal ArticleDOI
Effects of ordering type and degree on monoclinic distortion of 18R-type martensite in Cu-Zn-Al alloys
TL;DR: In this paper, a rigid hard sphere model for the M18R structure is developed by introducing the modified Bragg-Williams-Gorski-type order parameters, and the distortion in the close-packed plane in- creases with increasing degree of B2 order or with decreasing degree of L21 order is investigated.

The aging effect on Cu−Zn−Al shape memory alloys with low contents of aluminum
S. S. Leu,Chen-Ti Hu +1 more
TL;DR: In this paper, the effects of various quenching and aging treatments, including up-quenching (UQ), DQ, and step quench in a water bath at 100 °C (SQWB) and in an oil bath in an SQOB, have been studied on two Cu-Zn-Al shape memory alloys (SMA's) with the aluminum content less than 3.8 wt pct.

Electron microscopy of internally faulted Cu-Zn-Al martensite
S. Chakravorty,C.M. Wayman +1 more
TL;DR: In this paper, the authors showed that a thermoelastic transformation from a DO3 parent to an 18R martensite takes place using a Burgers vector at the parent interface on every third (001)18R plane in a Cu68Zn15Al17 alloy employing transmission electron microscopy.
Journal ArticleDOI
Atomic displacements in the austenite–martensite transformation
M. A. Jaswon,J. A. Wheeler +1 more
TL;DR: In this paper, the atomic displacements in the transformation from austenite to martensite are described and the strains involved are derived, and it is shown that the tetragonality arises as a necessary consequence of the assumption that the iron and carbon atom displacements constitute a common homogeneous deformation.
Journal ArticleDOI
X‐Ray Measurement of Long Range Order in β‐Brass
D. Chipman,B. E. Warren +1 more
TL;DR: In this article, the long range order in β-brass was determined by measuring the integrated intensity of the (100) superstructure reflection from a single crystal held at various temperatures, using a balanced NiCo filter.
