    PROBLEM TO BE SOLVED: To efficiently remove elements for accelerating crystallization from a crystalline semiconductor film. SOLUTION: An Ni film 13 is formed in contact with a semiconductor film 12 that is made of an amorphous silicon film, a microcrystalline silicon film, or the like. The semiconductor film 12 is heated at deg.C for moving Ni to form a crystalline semiconductor film Pv Elite [vlr00zp20wlz].

A second example is the Ni alloy, Udimetwith mass composition of 15% Cr, % Co, 5% Mo, % Ti, % Al, % C and % B. The thermodynamic parameters were taken from Ref.

[ 40 ]. The phase formation sequences are given in Table G2, the phase fractions in Fig. G4 and d H S /d T S and the DTA signals in Fig. The temperature gradient is eventually small in the uphill quenching process.

For example, for an Al–Si–Mg alloy, the temperature difference between solution treatment temperature and quenching is °C (SHT °C to warm water °C). 75 On the contrary, in uphill quenching the temperature difference is °C ( °C.

The Al sample alloy was cast at the Alcoa Technical Center with the composition listed in Table 1. It contains a total of 11 components. The alloy was first directionally solidified, and then its microstructure and microsegregation examined using metallography, scanning electron microscopy (SEM), image analysis, X-ray map and by: The crystal growth and orientation relationship of α Al and Si phases were investigated during eutectial crystallization.

Pure AlSi-alloy with 11 wt.% Si was unidirectionally solidified. Abstract. This paper describes research begun in the late s at the University of Southern California and continued since at the Illinois Institute of Technology with the objective of understanding the process of solidification at high growth by: 1.

The uncertainties associated with the crack growth process are incorporated assuming them as random variable following a statistical distribution.

The effect of material nonhomogeneity is included in the model through a random process parameter of Gaussian by: 1. Phase partitioning and site-preference of hafnium in the ME, has the composition Ni– Al– Cr– Co Aluminum atoms were incorporated in situ during the growth process.

This book is packed with more than photos, along with numerous tables and graphs. It will appeal to engineers who need or want to use copper alloys and need data on the potential corrosion problems and, specifically, how to avoid them.

Boratto et al. Tnr C ( Nb KIVCET smelter is a modern direct smelting process which has been used to replace conventional sinter/blast furnace technology in pyrometallurgical process of lead and zinc. Although heavy metals including Cd, Pb, Zn, Fe as well as S, O and Cl, are the main elements playing a leading role in the formation of molten phase on the waterwall tubes of the KIVCET waste heat boiler, hot corrosion.

It was also concluded (Schieber et al., ) that detector performance correlates with crystal perfection. The gamma ray rocking method was used to preevaluate small seed crystals in ampules selected for mercuric iodide microgravity vapor growth experiments on Spacelab 3 (SL-3) and the International Microgravity Laboratory 1 (IML-1).

Surface undulations known as rumpling have been shown to develop at the surface of bond coats used in advanced thermal barrier coating systems. Rumpling can result in cracking and eventual spallation of the top coat. Many mechanisms to explain rumpling have been proposed, and among them is a.This banner text can have markup.
