William Hume-RotheryDied 27 Sep 1968 at age 69 (born 15 May 1899).British metallurgist, internationally known for his work on the formation of alloys and intermetallic compounds. During WW II, he supervised many government contracts for work on complex aluminium and magnesium alloys. He established that the microstructure of an alloy depends on the different sizes of the component atoms, the valency electron concentration, and electrochemical differences. Hume-Rothery rules are an empirical guide to when two metals are sufficiently similar to be completely miscible (form a single phase at all relative concentrations). They are: (1). Atomic radii no more than about 15% different. (2). Pure metals have the same crystal structure. (3). Atoms have similar electronegativities. (4). Atoms have the same valence. |

MAGIC SQUARE: Calculate A-B+C
The aim is to place the some numbers from the list (2, 8, 9, 10, 15, 16, 17, 23, 24, 25, 57, 61) into the empty squares and squares marked with A, B an C. Sum of each row and column should be equal. All the numbers of the magic square must be different. Find values for A, B, and C. Solution is A-B+C.
