Faster cooling rates (100 \u00b0C\/min, 2000 \u00b0C\/min) at 920 \u00b0C promoted a bi-lamellar \u03b1 structure, with 2000 \u00b0C\/min enhancing strength. Lower HIP temperatures (800 \u00b0C, 200 MPa) minimized coarsening, improving strength, while slow cooling (12 \u00b0C\/min) led to the highest strength by limiting orthorhombic martensite formation. At 1050 \u00b0C, HIP reduced crystallographic texture and resulted in equiaxed prior-\u03b2 grains, improving isotropy, but the 2000 \u00b0C\/min cooling rate did not prevent grain boundary \u03b1 formation, which lowered strength and elongation.
