The parameter ϵ is called the defect. This paper considers bipartite graphs of defect at most 4, and presents all the known such graphs. Bipartite graphs of defect 2 have been studied in the past; if Δ≥3 and D≥3, they may only exist for D=3. However, when ϵ>2 bipartite (Δ,D,−ϵ)-graphs represent a wide unexplored area. The main results of the paper include several necessary conditions for the existence of bipartite (Δ,D,−4) -graphs; the complete catalogue of bipartite (3,D,−ϵ)-graphs with D≥2 and 0≤ϵ≤4; the complete catalogue of bipartite (Δ,D,−ϵ)-graphs with Δ≥2, 5≤D≤187 (D≠6) and 0≤ϵ≤4; a proof of the non-existence of all bipartite (Δ,D,−4)-graphs with Δ≥3 and odd D≥5. Finally, we conjecture that there are no bipartite graphs of defect 4 for Δ≥3 and D≥5, and comment on some implications of our results for the upper bounds of [formula could not be replicated].]]> Sat 24 Mar 2018 07:15:16 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:22092 0.67. It was found that a TiC nanocrystalline phase was formed under the high dose irradiation. However, a complete decomposition by irradiation did not take place even at 10.3 dpa. Post irradiation annealing to temperatures of 500–800 °C results in crystal regrowth of Ti₃SiC₂ and TiC phases.]]> Sat 24 Mar 2018 07:15:15 AEDT ]]>
