Creep Rupture Strength and Microstructure of Low C-10Cr-2Mo Heat-Resisting Steels with V and NbSpringer Science and Business Media LLC - Tập 12 - Trang 1071-1079 - 1981

The new ferritic heat-resisting steels of 0.05C-10Cr-2Mo-0.10V-0.05Nb (Cb) composition with high creep rupture strength and good ductility have already been reported. The optimum amounts of V and Nb that can be added to the 0.05C-10Cr-2Mo steels and their effects on the creep rupture strength and microstructure of the steels have been studied in this experiment. The optimum amounts of V and Nb are...... hiện toàn bộ
The Thermal Effect in Pseudoelastic Single Crystals of β-CuZnSnSpringer Science and Business Media LLC - Tập 12 - Trang 1491-1494 - 1981
L. C. Brown
The thermal effect associated with the formation and reversion of stress-inducedβ2 martensite has been studied in single crystals of β2-CuZnSn. The martensite in this system forms as isolated plates of β2 which increase in number and ultimately coalesce. The maximum temperature pulse obtained increased with fraction of specimen undergoing transformation and reached a maximum for complete transform...... hiện toàn bộ
Analysis of nonisothermal transformation kinetics; tempering of iron-carbon and iron-nitrogen martensitesSpringer Science and Business Media LLC - Tập 19 - Trang 925-932 - 1988

A powerful method for the analysis of solid-state transformation kinetics can be based on non-isothermal analysis where the temperature corresponding to a fixed stage of transformation is measured as a function of heating rate. Adoption of a specific kinetic model is not required for valid application of this method. This removes constraints imposed unnecessarily on so-called Kissinger-like proced...... hiện toàn bộ
The transition from columnar to equiaxed dendritic growth in proeutectic, low-volume fraction copper, Pb−Cu alloysSpringer Science and Business Media LLC - Tập 23 - Trang 1807-1815 - 1992
Shinwoo Kim, R. N. Grugel
Lead, 17.1, 11.2, and 5 volume fraction copper (14, 9, and 4 wt pct Cu) alloys have been directionally solidified at constant growth velocities ranging from 1 to 100 μm s−1. Serially increasing the growth velocity within this range results in a graded microstructural transition from fully columnar, albeit segregated, copper dendrites in a lead matrix to one consisting only of equiaxed grains. The ...... hiện toàn bộ
The stable and metastable Ti-Nb phase diagramsSpringer Science and Business Media LLC - Tập 19 - Trang 2389-2397 - 1988
D. L. Moffat, U. R. Kattner
The phase transformations which occur in the Ti-Nb binary alloy system have been discussed in two recent papers. The phase relationships were investigated by varying alloy composition and thermal history. In this paper, these results are summarized in complete and thermodynamically consistent calculations of the stable and metastable phase diagrams. The calculations of the metastable equilibria ar...... hiện toàn bộ
