“…Table 2 shows numbering of these samples. X-ray diffraction (XRD) in a Philips X'PERT MPD diffractometer using filtered Cu K␣ radiation ( = 0.1542 nm) was used to estimate the crystallite size and internal lattice strain of powders using Williamson-Hall method [16][17][18].…”

“…Hot pressing of blended powders provides a relatively simple means of creating a two‐ or three‐phase microstructure without the pitfalls of direct solidification; for this reason it is now widely used in processing of Mo‐Si‐B alloys. The technique has been used to successfully compact and sinter mixtures of molybdenum silicides, Mo and B,81, 113 precast Mo‐Si‐B powders,82–87 elemental Mo, Si and B114 as well as rapidly‐solidified,18, 19, 32, 95–101 surface‐modified,115–118 reaction synthesized15, 119–123 or mechanically alloyed4, 10, 11, 14, 123–137 Mo‐Si‐B powders. Heat treatment is required after hot pressing to further homogenize the material.…”

“…Mechanical alloying has received much attention recently4, 10, 11, 14, 124–137 as a method for producing ultra‐fine grained in situ Mo‐Si‐B composites. High energy collisions during mechanical alloying lead to repeated cold welding and fracturing of powder particles 138.…”

“…The peak shift toward higher angle can be related to lattice contraction. It has been reported [15,16] that Mo (Si, B) phase formation during high energy ball milling of a mixture of Mo, Si and B elemental powders is a result of the solubility of Si or B atoms into Mo. The mechanical alloying process can even form a supersaturated solid solution.…”
