Present studies in ph.sics assume th.t elementary particles are th. building blocks of all matter, and th.t th.y are zero-dimensional objects wh.ch.do not occupy space. Th. new I-Th.ory predicts th.t elementary particles do indeed h.ve a substructure, th.ee dimensions, and occupy space, being composed of fundamental particles called I-particles. In th.s article we identify th. substructural pattern of elementary particles and define th. quanta of energy th.t form each.elementary particle. We demonstrate th.t th. substructure comprises two classes of quanta wh.ch.we call “attraction quanta” and “repulsion quanta”. We create a model th.t defines th. rest-mass energy of each.elementary particle and can predict new particles. Lastly, in order to incorporate th.s knowledge into th. contemporary models of science, a revised periodic table is proposed.

Impact, tensile, and fatigue tests were performed in In783 alloy serving 4000, 23,000 and 48,000 h. Th. microstructure was th.n analysed by optical microscopy(OM), scanning electron microscopy(SEM), and transmission electron microscopy(TEM) to probe th. relationsh.p between microstructure and properties. Th. results sh.w th.t a new Ni_(5)Al_(3) ph.se is found, wh.ch.grows gradually in β ph.se with.serving time increasing,destroying th. martensitic structure of th. β ph.se, and degenerating th. tough.ess of th. β ph.se(approximately13.88% reduction). Th.refore, th. degradation of th. βph.se results in a sh.rp dropping of th. resistance to stress accelerated grain boundary oxygen(SAGBO) during serving;th.s, th. intergranular fracture morph.logy degree increases with.duration of service(almost 40% increase from th. fractured surface). In addition, th. strength.of alloy will be gradually enhanced wh.n th. γ'ph.se becomes relatively bulky with.serving time increasing due to considerable distortion of th. dislocations as a result of th. spacing of individual particles, in wh.ch.any movement of th. dislocation will h.ve to overcome a larger number of obstacles per unit length.
