On the origin of dynamic strain aging in twinning-induced plasticity steels
TL;DR: In this article, a diffusive jump of the C atom of the point defect complex in the stacking fault region is proposed to explain the room temperature dynamic strain aging in TWIP steel containing solute C.

The theory of an obstacle-controlled yield strength—Report after an international workshop
TL;DR: In this paper, the current status of the theory of yield strength was assessed at a workshop at Argonne National Laboratory (ANL) from May 29 to June 1, 1976, where six half-day sessions were held, each concentrating on one problem area, which was reported on by one or two speakers.

TL;DR: The tensile properties of Fe−18Mn−0.6C with Al-alloying additions of 0, 1.5 and 2.5 wt.% were investigated in the temperature range from 213k (−60k) to 413k (140k) as discussed by the authors.

The brittle-ductile transition in single-crystal iron
TL;DR: In this paper, the fracture behavior of single-crystal pure iron was studied by four-point bending of pre-cracked specimens at temperatures between 77 and 180 K and strain rates between 4.46

Mobility of Edge Dislocations in Silicon‐Iron Crystals
Dale F. Stein,J.R Low +1 more
TL;DR: In this paper, the velocities of unpinned edge dislocations in 3¼% silicon-iron have been measured as a function of stress over a range of five orders of magnitude in velocity from 10−7 cm/sec to 10−2 cm /sec.

The mechanical properties of iron single crystals containing less than 5 × 10−3 ppm carbon☆
D.F Stein,J.R Low,A.U Seybolt +2 more
TL;DR: In this paper, a method was developed to reduce carbon, nitrogen, and oxygen to low levels in iron using a radioactive tracer technique to analyze for carbon in iron, and it was shown that carbon can be reduced to less than 0.005 p.p.m.

The Mechanical Properties of Pure Iron Tested in Compression over the Temperature Range 2 to 293 degrees K
TL;DR: In this paper, the authors measured the mechanical properties of pure iron single crystals and of polycrystalline specimens of a zone-refined iron and found that macroscopic deformation at low temperatures is governed by some kind of lattice frictional stress acting on dislocations.
Journal ArticleDOI
The effect of carbon on the strain-rate sensitivity of iron single crystals
TL;DR: In this paper, the strain-rate sensitivity of iron crystals containing carbon in the range of 0.005 to 500 pm has been examined at 298° and 198°K and it was concluded that strain sensitivity of the crystals cannot be adequately explained on the basis of a single thermally activated process.

Experimental techniques for observing dislocations by the Berg–Barrett method
TL;DR: Experimental problems in the application of the Berg-Barrett Method to the observation of dislocations in metal single crystals are discussed in this article, where a criterion for selecting an appropriate filter to discriminate against the background noise is presented.
