It is described that the effectual way to construct phase diagrams is the combination of computer calculation with some critical measurements. Examples of application to the CuO-RE2O3 (RE. La, Y, Nd), Na2B2O4, K2B2O4 and PrCl3-CaCl2-MgCl2 systems are given

Under appropriate cooling condition, intcrfacial phase appeared between α and β phases in Ti-5Al-2M0-3Zr alloy. Its thickness could reach 100 nm. The interfacial phase was either single layer structure or double layer structure. The monolithic layer adjacent to 3 phase was indentified as fee structure with relationship (110)β// (001)m, [11$\\mathop 1\\limits^{{\\rm{ - - }}} $]β /[110]m. The striated layer adjacent to a phase was indentified as hep with twin relationship {10$\\bar 1$1}<1$\\bar 0$12> to α. Thus, the study provided a new experimental fact for the controversial topic on structure of striated layer. Chemical composition of interfacial phase varied slightly with heat treatments, but always between that of α and β phases

The role of Mg in alloy/718 has been systematically investigated. Mg raises not only high temperature tensile and stress-rupture ductilities but also increases considerably smooth and notch stress-rupture life. Mg containing alloy 718M is free of stress-rupture notch sensitivity. Mg improves creep and fatigue interaction properties (LCF or cyclic stress rupture) at any grain size. The basic role of Mg is equilibrium segregation at grain boundaries which helps to change continuous grain beundary (5-Ni3Nb morphology to discrete globular form which has a retardation effect on intergranular fracture. Mg promotes the change from intergranular to transgranular fracture mode
A pendulum is a rigid body suspended from a fixed point (hinge) which is offset with respect to the body's center of mass. If all the mass is assumed to be concentrated at a point, we obtain the idealized simple pendulum. Pendulums have played an important role in the history of dynamics. Galileo identified the pendulum as the first example of synchronous motion, which led to the first successful clock developed
In the previous lecture, we related the motion experienced by two observers in relative translational motion with respect to each other. In this lecture we will extend this relation to our third type of observer.That is, observers who accelerate and rotate with respect to each other. As a matter of illustration, let us consider a very simple situation, in which a particle at rest with respect
Gene mutation and evolution Gradual accumulation of mutations over long periods of time results in new biological species, each with a unique DNA sequence. Mutations and stabilization of mutations to new species. Charles Darwin: Unifying evolution theory-the origin of species from a common ancestor
Exercises 5(15) 1. Write a class with one virtual function and one non-virtual function Inherit a new class, make an object of this class, and upcast to a pointer of the base-class type. Use the clock( function found in (you'll need to look this up in your local C library guide) to measure the
Two tendencies often occur in the process of translation. One is going after smooth reading and beautiful language at the expense of the true meaning of the original, the other is rigidly sticking to the original words, and the translation turns out to be obscure [ əb'skjuə ] 难解的,含糊的and hard to understand
