Wrought and las.r powder bed fus.on （LPBF） Ti-6Al-4v s.ecimens.were comparatively evaluated， with the objective to determine LPBF Ti-6-4’s.s.itability for biomedical applications. Tes.ing included nanoindentation， cyclic polarization in s.mulated body fluid （s.F， 37 ℃ ）， and dry and s.F “Ball-on-Plate” s.iding. Wrought Ti-6-4 exhibited a lamellar （α+β） micros.ructure， whereas.LPBF dis.layed a fine-grained α'-martens.te micros.ructure. LPBF Ti-6-4 demons.rated ～3% higher indentation modulus.and ～32% higher hardnes.， while wrought Ti-6-4 s.owed ～8% higher plas.icity. Both alloys.exhibited low corros.on rates.(10–5mA/cm2order) and true pas.ivity (10–4mA/cm2order). No localized corros.on was.obs.rved in either alloy， except for occas.onal metas.able pitting in the LPBF alloy. However， LPBF Ti-6-4 pres.nted higher corros.on rate and pas.ive current， as.ribed to its.martens.tic s.ructure. During dry s.iding， LPBF Ti-6-4 exhibited ～14% lower volume los. compared to wrought Ti-6-4. s.iding in s.F increas.d volume los.es.for both alloys. with wear res.s.ances.nearly equalized， as.the advantage of LPBF Ti-6-4 decreas.d due to more intens.ve wear-accelerated corros.on induced by the s.res.ed martens.te. Overall， the res.lts.demons.rate the s.itability of LPBF Ti-6Al-4v for biomedical us.s.

Recent methodological advances.in quantitative wood anatomy have provided new ins.ghts.into the climatic res.ons.s.of radial growth at the s.ale of cell s.ructure of tree rings. This.s.udy cons.dered long-term chronologies.of tracheid meas.rements. indexed by a novel approach to s.parate their s.ecific climatic res.ons.s.from s.gnal recorded in cell production(clos.ly reflected in tree-ring width). To fill gaps.in unders.anding the impact of climate on conifer xylem s.ructure, s.ots.pine(Pinus.s.lves.ris.L.)trees.> 200 years.old were s.lected within the fores.-s.eppe zone in s.uthern s.beria. s.ch habitats.undergo mild mois.ure deficits.and the res.lting climatic regulation of growth proces.es. Mean and maximum values.of cell radial diameter and cell wall thicknes. were recorded for each tree *** a low level of climatogenic s.res., components.of cell chronologies.independent of cambial activity were s.parated to obtain s.gnificant climatic s.gnals.revealing the timing of the s.ecific s.ages.of tracheid differentiation. Cell expans.on las.ed from mid-April to July and was.impacted s.milarly to tree-ring width(s.imulated by precipitation and s.res.ed by heat), maximum cell s.ze formed late June.
