In this paper, we discuss the properties of simple modules over Auslander regular rings with global dimension at most 3. Using grade theory, we show the right projective dimension of ExtΛ1(S,Λ)$\begin{array}{} \text{Ext}_{{\it\Lambda}}^{1}(S,\ {\it

Ti-45Al-7Nb alloys are produced by liquid-metal-cooling (LMC) directional solidification (DS) furnace with different temperature gradients (G) at a range of 40–80 K/cm. The growth directions of primary β phases and the deflection angles relative t

Microstructural refinement by two steps heat treatment in Ti-47Al-2Cr-2Nb at.% alloy, with samples' dimension of ⌀ 15 mm × 80 mm, is studied in this paper. A coarse fully lamellar microstructure can be refined to a near gamma (NG) one with a grain
