  Opisano charakterystyczne cechy pękania powierzchniowego obserwowanego po nadtapianiu laserem CO2 i Nd:YAG stopu Ti-6Al-4V. Obserwowano pęknięcia niezależnie od sposobu nadtapiania, penetrujące głęboko strefę przetopioną i w niewielkim stopniu zależne od sposobu nadtapiania. Przypisano obserwowane zjawisko przemianie martenzytycznej i (lub) naprężeniom cieplnym powstającym podczas gwałtownego chłodzenia.

  When transport is analysed for its safe delivery the focus is mainly on assessing the safety of roads and the risk of undesired events. These include road accidents, an occurrence which is relatively rare and random. Randomness means that accidents depend on several factors which are partly deterministic (can be controlled) and partly stochastic (random and unpredictable). The set of crash contributing factors can be classified...
