The publication includes the court cases of the honorary symposium “Advances within the technology and Engineering of Casting Solidification” (TMS2015, Orlando, Florida, March 15-19, 2015) held in honor of Professor Doru Michael Stefanescu, Emeritus Professor, Ohio kingdom collage and the college of Alabama, united states. The ebook encompasses the subsequent 4 areas:
(1) Solidification processing: theoretical and experimental investigations of solidification procedures together with castings solidification, directional solidification of alloys, electromagnetic stirring, ultrasonic cavitation, mechanical vibration, lively cooling and heating, powder bed-electron beam melting additive production, and so forth. for processing of metals, polymers and composite materials;
(2) Microstructure Evolution: theoretical and experimental reviews concerning microstructure evolution of fabrics together with prediction of solidification-related defects and particle pushing/engulfment aspects;
(3) Novel Casting and Molding Processes: modeling and experimental facets together with excessive strain die casting, everlasting casting, centrifugal casting, low strain casting, 3D silica sand mould printing, etc.; and
(4) Cast Iron: all points concerning forged iron characterization, computational and analytical modeling, and processing.

Why examine the speculation of test layout? even though it should be important to understand approximately unique designs for particular reasons, event means that a specific layout can infrequently be used without delay. It wishes model to deal with the situations of the scan. profitable designs depend on adapting common theoretical rules to the targeted constraints of person purposes.
Twenty-five years after its preliminary book, The Making of the Atomic Bomb continues to be the definitive historical past of nuclear guns and the new york undertaking. From the turn-of-the-century discovery of nuclear strength to the shedding of the 1st bombs on Japan, Richard Rhodes’s Pulitzer Prize-winning booklet info the technological know-how, the folks, and the socio-political realities that ended in the advance of the atomic bomb.
First released in either long island and London in 1881, at a time of heated debates over the connection among technology and faith, this e-book arose from Henry Calderwood's Morse lectures given in organization with Union Theological Seminary, long island in 1880. Calderwood, a Scottish clergyman, used to be professor of ethical philosophy at Edinburgh college for over thirty years.

The results will be discussed in relation to known theories about solidification of metals. Different types of experimental set up have been developed and used in the different opportunities. The experimental set up is in many cases uniq and will be presented together with the experimental results. The paper is a summury of the lecture given at the conference. The paper will mostly present results form alloys solidifiing by formation of dendrite crystals. Experiments and Results Introduction: A solidifiction process are often studied by thermal analysis or by unidirectional solidification experiments.
The energy balance is given by pCV V-T = V-(k V-T) + V - [ p ( h s + A,)V] Where, C = /;C, + / i Q , k =fik, + fsks, p=fpi + fsps, The subscript s and I denotes liquid and solid phases respectively. V is the velocity vector. The casting geometry is normally slender. ^ and fs are the volume fractions of solid and liquid. The following simplification and assumptions are imposed, 1. The shrinkage driven inter-dendritic liquid velocity does not contribute at the leading order for the energy balance.
