Wear of fine pearlite, nanostructured bainite and martensite
… from pearlite, nanostructured bainite to martensite by heat treatment, do not lead to significant differences in the wear rate. This is because the wear mechanisms change, for example from severe sub-surface deformation leading to sticking in the case of pearlite, to brittle detachment of …

In search of martensite : titanium-tantalum shape-memory alloy
… of varying compositions to induce formation of martensite was developed. Heat-treated alloys were then tested for SME and superelastic behavior by means of hot oil recovery tests and were characterized through optical microscopy. Metallographs of some of the samples were taken throughout the …

A microstructural examination of duplex ferrite -martensite corrosion resisting steels
… evolution of chromium containing duplex ferrite-martensite steels and examines the effects of the microstructure on the mechanical properties. Emphasis has been placed on determining the microstructural factors responsible for the persistent occurrence of anisotropy in a modified 12 wt% Cr steel …

Aging Effects in Copper-Zinc-Aluminium Shape Memory Alloys (Martensite, Bainite)
Aging in both the beta phase and martensitic state of Cu-Zn-Al alloys causes deterioration and instability of shape memory properties, even at moderate temperatures. These aging effects have been studied by electrical resistivity measurements and bend tests. The corresponding changes in …

Structures and properties of lath martensite in rapidly solidified and conventionally processed iron-nickel-manganese-(titanium) maraging alloys
The microstructural changes, precipitation reactions and the mechanical properties of rapidly solidified and conventionally processed Fe-Ni-Mn-(Ti) martensitic alloys aged at 400-550$\sp\circ$C up to 600 hrs have been studied. Upon aging from 400 to 550$\sp\circ$C, the alloys showed classical …

A new framework for the interpretation of modulated martensites in shape memory alloys
… high symmetry austenite phase to a low symmetry martensite phase. Often in SMAs, the austenite is a B2 cubic configuration that transforms into a Modulated Martensite (MM) phase. MMs are long-period stacking order structures consisting of cubic (110) basal planes. First-principles computational …
