“…[34] This method has been successfully applied in the fcc-bcc system to predict the transformation crystallography. [34][35][36] In this method, the geometry between any pair of vectors related by the transformation from the fcc a-Al matrix (a) to the bct (Al,Si) 3 Ti precipitate (t) phases can be expressed by a transformation strain matrix A, i.e.,…”

In this study, the rod-shaped particles in an Al-7Si-0.35Mg-0.12Ti (wt pct) casting alloy have been characterized using transmission electron microscopy. It is found that these particles invariably contain Ti, Al, and Si and that they have the structure of the equilibrium phase (Al,Si) 3 Ti. A near-rational orientation relationship is observed between the (Al,Si) 3 Ti particles and the a-Al matrix phase. For this orientation relationship, the long axes of the (Al,Si) 3 Ti rods are invariably parallel to the moire´planes defined by the intersection of closest-packed planes of the (Al,Si) 3 Ti and a-Al phases. In contrast to the (Al,Si) 3 Ti or Al 3 Ti particles form directly from the melt act as heterogeneous nucleation sites for aluminum grains and thus grain-refined Al-Si foundry alloys, the (Al,Si) 3 Ti particles are found to form during solution treatment at temperatures above 673 K (400°C). Their formation occurs in the center of aluminum grains and/ or dendrites which is Ti enriched due to partitioning during solidification. The low diffusivity of Ti in a-Al allows the particles to form in the Ti-enriched areas near the center of grains as the Ti concentration is not able to be homogenized during typical solution treatment times.

“…This model gives a reasonable explanation for the deviation between the close-packed directions (CPDs) and the results are consistent with the experimental observations in a number of systems. However, the invariant line does not always lie in the CPPs [8,9]. In other models, without the parallelism of the CPPs, the invariant line is required to lie in a slip plane, as one of the conditions in the PTMC, but this condition alone does not fix the OR.…”

“…For these cases, the two phases are usually related by the Kurdjumov-Sachs orientation relationship (KS OR): (1 1 1) f || (0 1 1) b and ½0 1 1 f || ½1 1 1 b . However, precise measurements have revealed a small deviation from the ideal KS OR [2,9]. For understanding this type of ORs and other associated features, various theoretical models have been proposed.…”

“…However, a resent study on a stainless steel showed a double deviation feature of OR [9,28]: according to a careful analysis with Kikuchi patterns, both the CPP and the CPD in the precipitate deviate evidently from their corresponding ones in the matrix. Therefore, the 2D models are inapplicable to this case.…”

“…Numerous experimental and theoretical investigations [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] have been made on the crystallography of the transformations between the face-centered-cubic (fcc) and bodycentered-cubic (bcc) phases in various alloys including NiCr alloy [8], Cu-Cr alloy [4,7], steels [2,9], and so on. The product phases often exhibit an elongated shape with the habit planes in an orientation near {2 1 1} f 1 [8,10] or {5 2 2} f [1][2][3]11].…”

Thermomechanical deformation is one of the most efficient and facile routes to tailor microstructure in structural materials for mechanical property enhancement. Herein, the Ce‐modified SAF2507 super duplex stainless steel (Ce‐SAF2507) is deformed at different levels from 30% to 90% at a cryogenic temperature (–196 °C) to achieve superior mechanical performances. Cryogenic rolling increase fiber texture and induce ultra‐fine grain refinement which brings grains to ≈10 nm in the selected steel. The high‐density dislocations and deformation twins in the cryogenically rolled Ce‐SAF2507 lead to the nucleation and growth of martensite. Increases in the martensite volume fraction and nanoscale grain refinement occur at higher deformation levels. Cryogenically rolled deformation results in the overall increase in the Ce‐SAF2507 hardness. A higher hardness increment of austenite–martensite dual‐phase compared to that of ferrite is attributed to the austenite–martensite's higher work hardening ability. Furthermore, the ultimate tensile strength and yield strength increase with the deformation level, but the elongation decrease. Observed microstructural evolutions induced by cryogenic rolling enunciate the superiority of the present method over conventional ones to promote steel’ mechanical properties.
