Available in PDF, EPUB and Kindle. Book excerpt: ATERIALS, ARMOR, DENSITY, COST EFFECTIVENESS*ARMOR, *LIGHTWEIGHT, *BORON CARBIDESLightweight, high modulus boron carbide was hot pressed to a density>98 percent of theoretical by alloying additions at a temperature of 1750C and a pressure of 3500 psi. The additives used were 5 percent sodium silicate and 0.5 percent magnesium oxide, added as magnesium nitrate and the mixture was ball milled with steel balls which introduced some iron in the final composition. Microstructure analysis indicated ultrafine-grained structure with average grain size of 0.55 micron. The process has been scaled up to provide 6 in. x 6 in. x 3/8 in. thick tiles, and eight tiles were supplied to AMMRC for ballistic evaluation, which will be the subject of a separate report.

Available in PDF, EPUB and Kindle. Book excerpt: 12 IN. X 12 IN. X 3/8 IN. THICKNESS WAS HOT PRESSED TO A DENSITY OF> 98% of theoretical by alloying additions at a temperature of 1750C and a pressure of 3500 psi. Chemical analysis reveals iron as the principal densification aid remaining in the hot pressed structure. Transverse rupture and elastic modulus tests were conducted on samples 1 3/4 in x 1/4 in. x .100 in. cut from a 12 in. x 12 in. tile. The data show the rupture strength decreasing from an average of 73.4 Ksi at room temperature to an average of 38.4 Ksi at 1400C. The elastic modulus decreases from 55.5 x 10 to the 6th power psi at room temperature to 35.5 x 10 to the 6th power psi at 1200C. Hardness measurements taken with a Knoop indenter (100 gm load) range from 2530 to 2670. (Author) Portions of this document are not fully legible.
