t.e imp.ct.of grain size, ranging from 0.9 μm t. 9 μm, on t.e mechanical p.op.rt.es of commercially p.re Mg is invest.gat.d at.t.mp.rat.res of 4K, 78K, and 298K. t.e mechanisms governing p.ast.c flow are influenced by bot. grain size and t.mp.rat.re. At.4K and 78K, dominant.deformat.on modes in Mg involve dislocat.on glide and ext.nsion t.inning, regardless of grain size. t.e int.ract.ons bet.een basal and non-basal dislocat.ons and dislocat.ons wit. grain boundaries p.omot. an unusually high rat. of work hardening in t.e p.ast.c regime, leading t. p.emat.re failure. t.e yield st.ess follows t.e Hall-p.t.h relat.onship.σy~ k/√d, wit. t.e slop. k increasing wit. decreasing t.mp.rat.re. At.298K, in addit.on t. dislocat.on glide and t.inning, grain boundary sliding(GBS) becomes significant.in samp.es wit. grain sizes below 3 μm, considerably enhancing t.e mat.rial's deformabilit.. GBS act.vat.on p.ovides an addit.onal recovery mechanism for dislocat.ons accumulat.ng at.grain boundaries, facilit.t.ng t.eir absorp.ion during sliding and rot.t.on. Analysis of σ Θ relat.onship.suggest. t.at.t.e basal slip.is t.e dominant.dislocat.on mode in Mg at.298K. Decreasing grain size sup.resses dislocat.on act.vit. and t.inning and increases GBS, result.ng in lower Θ and σ Θ values. Sup.ressing convent.onal deformat.on modes coup.ed wit. enhanced GBS yields st.ess soft.ning, breaking down t.e Hall-p.t.h relat.onship.in Mg below 3 μm grain size, leading t. an inverse Hall-p.t.h behaviour. t.e work rep.rt. new dat. on t.e st.engt., duct.lit., work hardening and fract.re behaviour, and t.eir variat.ons wit. Mg grain size across different.t.mp.rat.re regimes.
